Astrong electromagnet produces a uniform magnetic field of 1.60 t over a cross-sectional area of 0.190 m2. a coil having 160 turns and a total resistance of 23.0 ω is placed around the electromagnet. the current in the electromagnet is then smoothly reduced until it reaches zero in 20.0 ms. what is the current induced in the coil?

Which type of current is produced by a wire breaking magnetic field lines and changing the polarity? a. alternating b. direct c. straight d. alternating and direct

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

An object in mechanical equilibrium is an object
